Theory of Operation
The Front ControlModule isn't receiving a fuel volume signal over CAN B from the ClusterModule. The FCM has to send the PCM a fuel volume signal over CAN C. The signal the FCM sends over CAN C is implausible.

Code 700 is a generic code that means there is a problem with the transmission control module. It could be the module, or something else causing the module not to work correctly.
You would need a scanner and a repair book to get the test procedure.

The location of the unit is under the dash by the steering column. In order to check it you would need an ohmmeter to properly test the operation of the unit. Once you have located the unit repost or comment on the question again and I'll post proper documentation on testing procedures.

It means "Crystal Clear Display"but in basic term its called a ccd bus, basically the OH console module is not communicating with body control module so you want to check power and ground pins or you just might have a bad module, sorry.A self-diagnostic test is used to determine that thecompass mini-trip computer module is operatingproperly electrically.CCD communications test.Following completion of these tests, the compassmini-trip computer will display one of threemessages: “PASS,” “FAIL,” or “CCd.”if the “CCd” message is displayed, the use of aDRBt scan tool and the proper Diagnostic Proceduresmanual are required for further diagnosis.

I would start with disconnecting the EATC / EMTC ( Electronic Automatic / Manual Temperature Control ) panel.Open the ash tray, and pull each lower corner out, they are held on with spring clips. Working your way up the center trim panel, there are 6 ( 3 on each side- black circles in the picture above ).When you get to the top, be cautious, the Passenger side airbag deactivation lamp has small wires on it, don't pull too hard ( green circle above )On the back of the EATC / EMTC panel are 2 cam over connectors ( blue circles in the picture above ), release the cam tab, and they will disconnect. When you reconnect it, it will default to off. Next is to run the self test calibration process ( pay attention to the temperature range ).

I have found some times the EATC / EMTC panel will just freeze up, and disconnecting it, and recalibrating it will make it work again. Few of them have not seen a problem again in 2+ years.Electronic Automatic Temperature Control Module On-Demand Self-Test The EATC module on-demand self-test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the EATC module on-demand self-test. Make sure to retrieve continuous DTCs by carrying out the Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs procedure before clearing any continuous DTCs.

•The EATC module on-demand self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.•The EATC module on-demand self-test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°-38°C (40°-100°F) when performing the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.•The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.•To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds . The display will show a flashing blower icon for 20 seconds , after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present the EATC module will display "00 00" and then on-demand DTCs. Record all DTCs displayed.•If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the Electronic Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given. See: Diagnostic Trouble Code Descriptions•If a condition exists but no DTCs appear during the self-test, GO to Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation.

The EATC module will exit the self-test and retain all DTCs.•To exit the self-test and clear all DTCs, press the DEFROST button. The EATC module will exit the self-test and all DTCs will be cleared.•Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited, the ignition switch must remain ON for at least 30 seconds to allow the door actuators to automatically recalibrate.•Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

Electronic Automatic Temperature Control (EATC) Module and Electronic Manual Temperature Control (EMTC) Module Cold Boot Process The purpose of the cold boot process is to allow the EATC or EMTC module to re-initialize and calibrate the door actuators. To carry out the cold boot process, follow the steps below.

1.Turn the ignition switch to the OFF position.2.Disconnect the EATC or EMTC module electrical connectors.3.Wait one minute .4.Connect the EATC or EMTC module electrical connectors.5.Turn the ignition switch to the ON position.6.Select any position except OFF on the EATC or EMTC module. The EATC or EMTC module will now initialize and calibrate the mode doors. Calibration of the mode doors will take approximately 30 seconds .
